To fix this problem temporarily, I did the following:
$ cd /usr/share/icons
$ sudo cp -r Humanity Humanity-fixed
$ cd Humanity-fixed
$ sudo vi index.theme
Change the theme name to "Humanity-fixed", then :wq to save the file
$ sudo find . -name \*delete\* -exec rm {} \;
Then go into the Theme tab on System->Preferences->Appearance, Customize your theme and choose Humanity-fixed from the Icons tab, and the GNOME trashcan icon will be used instead.
Of course, this also means that fixing this problem is simply a matter of removing the offending icon files from the theme.
